Abstract	In the advanced nuclear power plants including APR1400, the SDVS has been adopted to increase plant safety using the concept of a feed-and-bleed operation. In the case of the TLOFW(total loss of feedwater) in a PWR(pressurized water reactor), the POSRV(power operated safety relief valve) located at the top of the pressurizer is expected to open due to the pressurization of the reactor coolant system and discharge steam and/or water mixture into the water pool, where the mixture is condensed. During the condensation of the mixture, thermal-hydraulic loads such as pressure and temperature variations are induced in the pool structure. For pool structure design, such thermal-hydraulic aspects should be considered. Understanding the phenomena of submerged steam jet condensation in a water pool is helpful for system designers to design proper pool structures, spargers, and supports etc. This paper reviews and evaluates steam jet condensation in a water pool for the physical phenomena of steam condensation including condensation regime map, heat transfer coefficient, steam plume, steam jet condensation load, and steam jet induced flow.
